Windows 11 (24H2) 26100.8117 IoT Enterprise x64 Emergency Update

This emergency update fixes "(0x80073712)" potential installation error message.

After rolling out an optional non-security update for Windows 11 last week, Microsoft was forced to pull it due to widespread installation issues. The cumulative update KB5079391 included several quality improvements; however, users reported that it failed to install, showing error code 0x80073712. To replace the faulty preview update, it has now issued an out-of-band KB5086672 emergency update for affected Windows 11 25H2 and 24H2 systems.
